Q:7 square feet of aisle to install 3 LED downlight, how much w led downlight
5W*3, the key depends on the ceiling elevation.You can use 3 W
Q:LED lamp is mainly used in where
Downlight is generally used in shopping malls, offices, factories, hospitals and other indoor lighting, the installation is simple and convenient for people to love. LED downlight downlight all inherited the traditional advantages, less heat, energy saving and long service life, small maintenance costs. The early LED lamp LED lamp due to expensive, the overall cost is very high is not acceptable to the customers. With the decrease of LED lamp chip prices and cooling technology improved, laid a solid foundation for the LED lamp into the commercial field.
Q:Turn off the lights after the bright LED lamp
Because the electrician is working on the power off switch, the power switch is a zero line, not a live wire. Electricians know that the power switch must be cut off by the line of fire, and no danger of electric shock is announced. If the power switch is on fire line, after the power is cut off, the FireWire will continue to supply power to the LED driver. Therefore, the LED lamp will have a faint light when the switch is turned off.
Q:Why use LED lamp light source patch
In a large number of automated production, the packaging cost of the patch LED itself and the cost of soldering to the circuit board are lower than those of the small power LED.
Q:How much is the general 15WLED lamp luminous flux.
Look at the product parameters, and if it's done with a single 1W, it's probably around 1600LM,
Q:What brand of downlight is good? Please explain the reason, thank you!
Quality. After deciding to buy LED lights, you'll have to see what quality LED lights you need. At present, the country has not yet introduced LED lighting quality standards, so the market LED product quality is uneven, some very cheap brand-name goods using the chip quality is very poor, that is 1W, only 0.5W-0.7W, and manufacturers in order to do high brightness, it will increase the output current of power supply, it will cause serious decay. Should choose some brands of their own products, such as "one enterprise", "Hangzhou ray", "silver rain" and other brands.
Q:Excuse me, how to install the LED lamp?
According to the instruction, the hole is opened on the ceiling with an openerThree: after opening the hole, pull out the wire, then connect the drive and the lampPay attention to the positive and negative poles of the lamps and lanterns, the ground mark of the lamps and lanterns, and correctly install the ground wirePay attention to the distance between the fixtures and the wall or the wall so as to facilitate the heat dissipation of the lamp
Q:LED lamp power off why would light up
LED lamp power off, will light up, this situation is normal in the 220 electric power supply situation, reason is caused by the distributed capacitance charge discharge line.Because the switch and the lamp is connected with 220V/50Hz AC power supply is normal, directly added to both ends of the lamp, the lamp work light; when closed, switch capacitor and lamp itself and the line is connected to the alternating current of 220V/50Hz, because the distributed capacitance of the charge and discharge can form weak current, the lamp will light.Solution: in the lamp circuit board input end in parallel with a pressure resistance of at least 400V of non-polar capacitor, capacity 0.05 micro method above (if the switch connection is longer, can be appropriately increased).
Q:Steam more business bathroom bath with what LED lamp?
LED is the heat source, and belongs to the heat dissipation lamp lamp, the panel is also very hot, and the hot surface is not fog, dew condensation, which is the basic common sense, so do you have anything to worry about. The so-called "anti fog lamp" on the Internet is nothing more than the high sealing degree of the panel and the soft light emitted by the semi transparent panel.
Q:How are LED lamp quality is good or bad?
Let LED down light up continuously for several minutes, feel the temperature, touch the radiator, LED lamp behind the hand, such as hot feeling pain, showed that LED downlight overall temperature is too high, easy to damage. The quality of the product is considered substandard.
